The correct answers are Maintenance, Production, and Engineering . In the Preparation Phase, the VM Facilitator must ensure that the right stakeholders and technical participants are involved before the study begins. SAVE describes Value Methodology as a systematic process performed by a multidisciplinary team led by a qualified facilitator to improve value. ( Value Engineering ) The selected participants should represent the areas directly affected by the subject under study.
Because the new product affects the current manufacturing process , the most relevant input must come from those who understand the physical process, equipment, workflow, capacity, and technical requirements. Production provides knowledge of daily operations, labor flow, throughput, bottlenecks, quality issues, and feasibility on the shop floor. Maintenance provides input on machine reliability, downtime risk, service access, preventive maintenance needs, and equipment limitations. Engineering contributes design, tooling, process capability, specifications, manufacturability, and technical integration.
Marketing may help define customer demand or product positioning, but the question specifically focuses on manufacturing-process impact. Human resources may support staffing or training later, but it is not one of the primary technical input sources for process change.
